Kits available on request
• Kit of system shutoff valves (on request). The boiler is fitted for installing
the system shut-off cocks on the delivery and return pipes of the
connection unit. This kit is extremely helpful for maintenance as it permits
HU
draining the boiler alone without having to drain the entire circuit as well.
• Polyphosphate batching kit (on request). The polyphosphate batching
unit prevents the formation of limescale over time and maintains constant
heat exchange conditions and production of domestic hot water. The
RU
boiler is designed for application of the polyphosphate batching unit.
The above kits are supplied complete with instructions for assembly and
use.
